In BS8006, the two-part wedge method and the log-spiral method is recommended for analyzing the stability of soil nailed slopes. SnailPlus reports can include tables and graphs with all examined model properties and calculated results. 0000146518 00000 n This spreadsheet was developed based on the FHWA Method presented in Publication No. The Wizard creates the modelautomatically, saving us a lot of time and effort for the initial creation. Build on solid fundamentals on the design of deep excavations, and learn how to minimize uncertainties. Shotcrete or concrete is typically applied on the excavation face to provide continuity when a soil nail wall is constructed. - Improved control and report for temporary facing conditions (single layer), - Improved earth pressure calculations for irregular surface conditions, - Available shear analysis method, - FHWA LRFD methods for shotcrete, - Improved output reports, Soil nail wall excavation in Pennsylvania difigned with SnailPlus. This means that you can include all intermediate construction stages for your soil nail wall, include 3D loads, all in an interactive environment. Consider the distance the nails will project behind the wall and any potential conflicts with subsurface obstruction or right of way limitation.
